KAIGAKU's true strength was explained

Kaigaku was a former disciple of Thunder Breathing Hashira -Jigoro Kuwajima with Zenitsu. Kaigaku, a talented devil slayer, was not satisfied with his ability and wanted to be stronger. This is when he gave up mankind and chose to become a devil.

Unlike Zenitsu, Kaigaku was able to learn almost all thunder breathing, but was arrogant and proud. After becoming a devil, Kaigaku has become stronger by increasing speed, endurance and blood demon art. His thunder breathing became darker energy and became more powerful because of the new form.

Kaigaku's thunder breathing and evil evolution

From the devil slayer to the devil, Kaigauku chose evil on the line.

As a devil, Kaigaku's body adapted to improve the combat style and thunder breathing was more fatal. He was now a devil, so he gained trademarks such as regeneration and durability improvement, making it a powerful force for dealing with him. His thunder breathing style now injects his Blood Devil Art and produces dark lightning, and he could interfere with more powerful attack than his original thunder. Even the powerful members of the DEMON Slayer Corps members will be difficult to follow Kaigaku's speed and force along with his electrical evil attacks.

Kaigaku has swallowed many humans to become stronger, which has given the superiority to be stronger with the blood of Mujang. KAIGAKU was a former disciple of Jigoro and had an excellent sword with amazing technology for thunder. His blood demon art has improved Kaigaku's swordsmanship further and more dangerous. Kaigaku says his adaptation to blood demon art can surpass thunder because of the ability to manipulate real lighting and electricity. No matter how skilled Kaigaku, he could not learn Thunderclap and Flash, the first and most fundamental form of thunder. He was able to execute all five other thunder breathing techniques, but lacked the most important skills. His rival, Zenitz, was able to learn the first form and master it perfectly. It is speculated that this led to the fall of Kaigaku. Zenitsu was able to use the transformation of thunder breathing. The first form was able to destroy Kaigaku.

KAIGAKU's blood devil art -electricity

Was Kaigaku truly a strong demonstration?

Kaigaku's Blood Demon Art is known as electrokinesis and complements thunder breathing to create and manipulate black lightning in the body and blood using special electrical abilities. This type of blood demon art is very fatal because it can create special effects that can be broken and severe burns in the other's flesh. Like the devil who transformed Kaigaku (Kokushibo), Kaigaku owned his original Katana since he was DEMON Slayer. His physical blade can deliver electricity through blood when the attack can be delivered through blood, so you can run the attack using blood demon art.

DEMON Slayer: Why did Muzan be afraid of solar breathing technology?

Muzan is not afraid of much, but the sun's breathing crawls his skin. What is it special?

The Thunder Breathing Forms, which Kaigaku can run, were second, third, fourth, fifth and sixth, and each form is as powerful as the following format. Eventually, during Infiniti Castle Arc, Zenitsu was able to overwhelm Kaigaku by running a powerful thunder breathing form made to defeat Kaigaku, and left him as the only user of thunder. Unlike other upper moons with years of experience as a devil, Kaigaku was a devil for a short period of time, and it was not enough time to fully acquire unique Blood Devil Art. It may have been possible that Kaigaku could have defeated Zenitsu until Zenitsu waited longer and became more powerful.
